Another headbeaker I'm afraid, at least for me!
I thought I was on the right track thinking it being one of the Mucuna species, but found out the leaves of all Mucuna are always threefoliolate, mine is in pairs,
To make it even more complicated when i zoomed into one of my pics, i found some leaf arrangements trifoliolate!
Then i thought maybe it belongs to the Bignoniaea family, but got no further either. Problem is that i have no flowers, so i have not much hope, but one can only try..
The seedpods look prickly, but I did't try that out, having had bad experience touching the ones of Mucuna urens, oughhh! :lol:
